Apparatus and method for implementing a local proactive hot plug request/acknowledge scheme is disclosed. In a preferred embodiment, each hot pluggable device installable on a computer bus, such as a SCSI bus, is provided with a physical user interface comprising a mechanical request initiator, such as a button or two-position switch, for allowing a user to generate a hot swap request to a controller associated with the bus prior to actual installation of the device on, or removal of the device from, the bus. Upon receipt of the request, the controller determines whether the requested action may be performed, provides a visual indication of its determination to the user via an LED on the user interface and, if installation or removal is determined to be prudent, performs the hot installation/removal in an orderly manner so as not to adversely affect ongoing system operations.

Apparatus for implementing a local proactive hot swap request/acknowledge scheme in a computer system comprising a computer bus and a plurality of electrical devices each including a carrier, each device being physically and electrically connectable to said bus, the apparatus comprising: each of said carriers of said electrical devices including a user-actuatable means supported thereon for generating a request for a hot swap procedure in connection with said electrical devices comprising a hot installation or a hot removal of said electrical devices; processor means electrically connected to each of said user-actuatable means, for processing said hot swap request to determine whether said requested hot swap procedure may be performed without detrimentally affecting ongoing operations of said bus and said system, and for generating signals indicative of results of said processing; each of said carriers of said electrical devices including an indicating means supported thereon and electrically connected to said processor means, for indicating said processing results to a user, said indicating means being responsive to receipt of said generated signals from said processor means; and means connected to said processor means for performing said requested hot swap procedure when said processor means determines that said requested hot swap procedure may be performed.
